Bently Nevada Machinery Condition Monitoring

Description

The vb7 Portable Data Collector, Analyzer and Balancer
instrument is a dual channel vibration data collector,
analyzer and balancer. You can use this device for on-route
and off-route data collection, machine-sideanalysis and
diagnosis as well as on-site dynamic balance correction.

The vb7 Portable Data Collector, Analyzer and Balancer is
certified for Class 1Division 2 hazardous areas. It is
ergonomically designed and lightweight for all day comfort.

The vb7 provides recordings with up to 6,400 lines of
resolution and up to 40 kHz F
settling algorithm and 6Pack recording system offer quick,
one-step data recording.

The vb7 Portable Data Collector, Analyzer and Balancer has
plenty of storage and long battery life, and is backed by a five
year warranty.

The vb7 Portable Data Collector, Analyzer and Balancer is one
of Bently Nevada hardware monitoring assets that work with
System 1 software.
